 | |
| Subject: [PATCH] media: i2c: imx290: Group functions in sections
 | |
| 
 | |
| Upstream commit cb7e1c8dbe60
 | |
| 
 | |
| Move functions around to group them in logical sections, in order to
 | |
| improve readability. As a result, the IMX290_NUM_SUPPLIES macro has to
 | |
| be changed. No other code change is included, only moves.
